TO ALL WHOM IT MAY CONCERN:

Be it known that we, PETER ScHMI'rT and PETER JACOB SGHMITT, ofWaterloo, in the county of Monroe, and State of Illinois, have madecertain new and useful Improvements in Grain-Drill Shoes and we dohereby declare that the following is a full and clear descriptionthereof, reference being had to the accompanying draw ings, and to theletters of reference marked thereon. I

This invention relates more particularly to the coupling by means ofwhich the seed-shoe is attaehedto the other parts of the drill.Thedevice consists of two coupling-links, that are attached to thetraction-rod,

by means of a single pivot-pin,which allows a vertical play ofthe parts,and a similar attachment between the back ends of the said links and thelug-projecting from the front side of theshoe. A rivet-pin, connectingthe two 'links, passes through a segmental slot in the shoe-lug, andpermits the shoe to tip, when the machine is backed, but which holds theshoe in the properposition for dropping the seeds when it is drawnforward. A wooden pin is passed through holes in the links, and-one of aseries of adjusting-holes in the end of the traction-rod. By means ofthis connection, the shoe is adjusted at any inclination required, andthe adjustingpin is allowed to break should any hard obstacle beencountered by the pointof the shoe.

To enable those skilled in the art to make and use our improveddrill-shoe, we will proceed to describe its construction and operation.p p

Figure 1, of the drawings, is a sectional side clevationot' the improved'shoe, and its traction-rod, one of the connecting-links being removedin this view for the exhibition of the construction of the parts.

Figure 2 is a plan (if the same, but showing both connecting-links.

The shoe A is a metallic tube, through which the grain or seeds drop tothe ground, and is of the usual construction. Afiixed to the forwardside of this shoe,'and .near its top end, "is the lug a, through whichthe traction forceis transmitted, from the traction-rod B and links C,to the shoe A.

There should be two of the links C, one of which will be placed oneither side of the said rod and lug, and pivoted thereto .by means ofthe pins 6 and c, in such a manner as to permit a vertical play of theparts, except when restrained by the pins 6 and 0'. I

The pin 0' is of metal, and secured in the links by riveting orotherwise, and arranged to move up or down in the segmental slot a, ofthe lug a, so as to allow the shoe to tip, as represented by the dottedlines in fig. 1, i

when the machine is backed. V

The pin 6 should be of wood, which will enableit to be broken when thepoint of the shoe encounters a root, or stone, or other hard substance.Several holes, 12 should be provided in the back end of the rod B, so asto set the links in such a position as'to guide the point of the shoemore or less deep, as may be required.

Having described ourinvcntion, what we claim, is-' i 1. The shoe A, whenprovided with a slotted lug, a, and combined with the rod B and links 0,as herein described and shown.

2. The rod B, when provided with adjusting-holes b and coupled with thelinks C, by means of the jointpin 6, and the wooden pin 6'. r 8. Thearrangement of the curved slot a, pin 0', and links 0, substantially inthe manner herein shown and described.
